Returning to his residence from the test square, Qin Yu rested for a long time before the tyrannical aura in his chest subsided. This huge gap in strength made him understand that his physique was not enough, and he had to improve his strength to become stronger.

He took the cultivation card and took advantage of the night to head towards the cultivation ground.

Entering the cultivation ground, go through the usual outer sect disciples' cultivation place to the cultivation corridor, the left and right sides of the corridor are separate cultivation rooms, near the corner entrance are rooms 68 and 67, as long as there is a cultivation card on the door, it means that someone in it is cultivating.

Qin Yu took a step into the corridor, and as soon as he took a step, a hot breath rushed towards him. At first, I didn't think anything was abnormal, but as I went deeper, the physical exertion became more and more obvious. When I reached the door of the eighth room, it was a little difficult to even move my steps.

"Good~What a terrible consumption, whew~", Qin Yu said breathlessly while holding the stone door with both hands.

He moved the groove on the door of the cultivation card in his hand, and the heavy stone door was opened. Qin Yu walked into the room with his help on the stone wall, and the door slowly closed. If the physical exertion at the door is like a long run, then the physical exertion in this room now is like not eating for a few days.

Not only is his body weak, but even his spirit is a little sluggish. The first time he came to this cultivation room, Qin Yu's whole body softened, and his face made a direct intimate contact with the ground.

Qin Yu, who fell to the ground, almost fainted with his eyes blazing with Venus, now he was like a hungry ghost, and he couldn't wait for a meal full of delicious food in front of him.

"Look-it's not easy to come to the core disciple~", Qin Yu gritted his teeth and got up, and then sat down cross-legged on the spot. He sat motionless on the ground with the feeling of hunger, and his whole body was covered in cold sweat.

The light from the windows in the room was getting weaker and weaker, until the light in the room was provided by the crystals, and he sat motionless on the ground.

Now I am so hungry that my chest is close to my back, my mouth is full of saliva, and my brain is full of delicious food. I don't know how long it has been, but this hunger has not abated, but there is a trace of heat in my heart.

The temperature in the entire cultivation room was rising, and I was already very hungry, and the heat was even more exhausting. But while he was tormented, a pale blue flame had condensed around his body.

This was the flame of the Blue Flame Forging Body Technique, and in this flame wrapping, all the power of his body was withdrawn. The body without the support of the power has no resistance, and is constantly tempered in this blue flame.

While refining the body, the power of the withdrawn body was not lost like a normal person, but was all condensed in this blue flame.

The blue flame didn't have much temperature, but it was everywhere, Qin Yu only felt that every cell was hot and unbearable, and he didn't feel any improvement in his body strength.

Even so, he still held on in his heart, because if he wanted to be strong, he had to be strong. It's only three nights, and there's no extra time for him to get used to it before he comes back to practice.

Originally, I wanted to deliver the task of delivering the Xingwu Store while cultivating, but now it seems that I can't do it for the time being. As time passed, he didn't know whether he was adapted or paralyzed, and his heart was no longer restless at the beginning.

The night passed in a flash, the morning light shone into the room through the window, and Qin Yu opened the stone door and walked out of the cultivation room. When he walked out of the cultivation room, the blue flames on his body disappeared.

Suddenly, the extracted power returned to the body, just like the previous exchange of cultivation. Hunger and weakness were gone, and he didn't feel a trace of tiredness after a night of sleep. A powerful force circulated in his body, and then completely stabilized, Qin Yu stood at the door for a long time before coming back to his senses.

"It's worthy of the magic trick that once dominated the three sects, what a domineering ascension effect", Qin Yu clenched his fists and sighed, the ascension speed of this leap made him not want to leave.

The main thing is that there are no sequelae of this improvement, not only the strength has been improved, but the body has also become stronger, and it can perfectly withstand more powerful forces. With such a comprehensive and rapid technique, it is no wonder that the Lingyuan Sect was once able to sit firmly at the head of the three sects for thousands of years in the Blue Flame Forging Body Technique.

In other ways, either strength improvement requires physical exercise, or physical fitness requires strength. Just like the disciples of the Xuanyuan Sect need compound methods when they are cultivating. And the Qingyuan Sect is even worse, there is only one kind of magic breath in the cultivation room or cultivation ground, which can only improve the physique, and the strength improvement also requires the disciples to cultivate the magic tricks separately.

Although he wanted to spend three days on cultivation, the reality obviously did not allow it, and Qin Yu could only put away the cultivation card and leave. He was like a stimulant all day, and he was full of energy and vitality in everything he did.

Towards evening, everything was done. "Finally have time, Qianyi, take the Lingyuan that the store task wants", Qin Yu returned to his residence and was eating dry food.

I'm going to starve later, so I'll eat enough now. His voice fell, and the broken spirit in his hand shimmered with gold, and then he took the cold fire spirit snake spirit yuan in his hand.

After going to the northern valley to collect for half a month, Qin Yu basically knew the specific structure of the entire Xingwu Store, and the remnants left by his brother were currently a bridge with the system to transmit items.

"Received the Ice Cold Fire Spirit Snake Spirit Yuan, and cultivated to 10% of the completion of the exchange task", Qianyi's gentle voice sounded in his head.

"What?", Qin Yu was stupid, he thought that one spirit yuan could be directly exchanged for a five-fold cultivation of the body, but now he didn't expect the result to be 10%, he had a feeling of eating a rotten fly.

"Cultivation is exchanged for the next task to open: you need a third-order spirit beast Centennial Spirit Yuan", Qianyi's voice sounded again.

"Qianyi, can I stop doing this task, I feel like I've been cheated by you", Qin Yu was speechless.

"You don't have to, but the system won't return the materials you've already submitted," Qianyi said.

"In other words, it pit me a spirit yuan, meow. How do I think it's a black shop", Qin Yu was very helpless, it was impossible to get a five-fold physique overnight.

"Hehe, you don't have to say that, because the progress of the task is completed by one-tenth, the store will usher in the first batch of exchangeable things in ten days, as an administrator, you can specify the type of this batch of things", Qian Yijiao said with a smile, she and Qin Yu have gone from strangers to acquaintances in the past half a month.

"There are things that can be exchanged, what are the types", Qin Yu became excited again when he heard it.

"There are tricks, physical techniques, items, spirit animal materials, etc.," Qianyi said.

"You don't need a magic trick, the Blue Flame Forging Body Technique is very complete. The uncertainty of the item is too high, and I can't use the spirit beast or materials for the time being, so let's do it", Qin Yu made a decision after weighing it.

"Okay, in ten days, the exchange will arrive," Qianyi said.

"Tell me when you get there, I'll go to practice now. Since you can't exchange it, you can only repair it yourself", Qin Yu turned around and went out.

The two nights of penance passed quickly, Qin Yu was still a little unsatisfied, and the whole person was like being reborn for three nights, and this ever-increasing sense of fulfillment made him very reluctant.

But even so, what should be paid back still has to be returned, and at the same time three days later, Qin Yu went to the mission hall again with the cultivation card.
